Pedro Arsénio
Pedro Miguel Ramos Arsénio has a PhD in Landscape Architecture from Instituto Superior de Agronomia / Universidade de Lisboa (School of Agronomy, University of Lisbon) obtained in 2012. He began teaching in 1999 where he is now a lecturer, primarily engaged in the subjects of Landscape Planning and Geographic Information Systems. He also holds the positions of Head of the first cycle degree (Bachelor) programme in Landscape Architecture (since August 2013) and of Coordinator of “João de Carvalho e Vasconcellos” Herbarium (since November 2015), within the previously mentioned institution.
As a researcher he is, since January 2015, a member of “Linking Landscape, Environment, Agriculture and Food” (LEAF) Research Centre, researching mainly in the fields of Geobotany, Nature Conservation and Green Infrastructure Planning. His specialist areas of interest include vegetation mapping, applied phytosociology studies and ecological modelling of both species and plant community distributions. He has recently focused on researching the relationships between ecological quality and the visual quality of Mediterranean landscapes. He has also joined the interdisciplinary platform Food, Farming and Forestry (F3) – University of Lisbon, as well as TERRA Associated Laboratory.
He has sat on the Counseling Commission of Ajuda’s Botanical Garden (from August 2007 to December 2014), and at the Advisory Committee of Lisbon's Biodiversity 2020 Task Force (from March 2010 to September 2012). Presently, he sits (since November 2015) as the representative of his institution, School of Agronomy/Univ. Lisbon, in two national protected area’s (Arrábida Natural Park and Arriba Fóssil da Costa de Caparica Protected Landscape Area) Strategic Advisory Boards.
As a member and contributor of several phytosociological associations he has participated in the organization of various academic and scientific events, as well as geobotanical excursions.
His scientific outputs include the scientific co-edition of a book on Portuguese flora, the co-authoring of articles in both international and Portuguese scientific journals and the supervision of numerous master’s thesis.
Supervisors: Javier Loidi Arregui, Luís Paulo Ribeiro & José Carlos Costa

Paula Queirós e Cecília Sérgio) uma turfeira no Sado com Sphagnum auriculatum vivo (Lagoa da Batalha - Alcácer do Sal). Posteriormente a espécie tem vindo a ser encontrada progressivamente mais para Sul, primeiro no Estuário do Sado: Texugueiras; Claros - Moinho da Ordem e Cachopos e em 2009, pelos autores deste trabalho, na
arriba da Praia da Pedra da Bica, na Zambujeira do Mar (Odemira, Baixo Alentejo). Esta última localidade fica a cerca de 98 km para sul da posição mais setentrional onde a espécie é conhecida em Portugal, correspondendo também ao local mais a sul de toda a sua área de distribuição na Europa.
In this study, we investigated: (1) cytotype distribution and diversity within and among populations in an overlapping region of diploid and polyploid Limonium spp. in south-western Iberia and north-western Morocco; and (2) patterns of geographical parthenogenesis and ecological preferences across a latitudinal gradient on the Atlantic coast. We show here for the first time that L. nydeggeri and L. algarvense are found further south in Morocco than previously reported. Genome size and ploidy estimates showed that the distribution of these species is not random at the overlapping region studied: tetraploid apomicts tend to be found at higher latitudes than the sexual diploids and L. algarvense grows in sympatry at the southern boundaries of the diploids. Natural populations showed a constancy in ploidy in these complexes. However, we report for the first time the occurrence of mixed-ploidy populations of L. ovalifolium s.l., euploid triploids in L. algarvense and aneuploids in the L. binervosum complex. On the Atlantic coasts, L. algarvense followed by L. ovalifolium complexes occur significantly more frequently in thermomediterranean and dry ombrotype habitats than the L. binervosum complex. Significant differences were also observed among taxa in the frequency of occurrences on the most common lithological groups. In conclusion, this work presents the first biogeographical insights for the group based in a coarse-scale analysis of data and it provides evidence of ecological differentiation between the studied Limonium complexes.

A relação entre tipologia de uso do solo e o seu interesse para a conservação da natureza não é direta nem consensual para todos os tipos de uso. Partindo do princípio que, quando uma área é classificada é assumido que tem valor para a conservação e tendo por base a Carta de Uso e Ocupação do Solo, os Sítios de Interesse Comunitário e a localização das áreas de Habitats da Diretiva, determinou-se qual a frequência com que cada tipo de uso do solo foi classificado como Sítio de Interesse Comunitário e como Habitat da Diretiva, determinando assim o valor implícito de cada tipologia de uso do solo para a conservação dos Habitats, a nível nacional.
Foi analisada também a correspondência entre cada tipologia de uso do solo e as tipologias de Habitats da Diretiva, obtendo-se nos resultados correspondências muito significativas em particular com as quercíneas. No entanto, a base cartográfica desteshabitats carece de maior pormenorização para que possam ser determinadas correspondências para a globalidade das tipologias.
